## FormEmailAPI (Formpost)

FormEmailAPI is the current name of the service that previously ran as Formpost. It gives static sites, landing pages and framework-based front ends a functioning contact form without asking the developer to run a mail relay. You create a form in the dashboard, receive a dedicated submit endpoint, and paste that URL into the action attribute of your markup. Anything posted there is filtered, stored and emailed onward.

The product is deliberately not a widget. There is no iframe, no injected stylesheet and no badge, so the form keeps your own HTML and CSS on Vercel, Netlify, Astro, Next.js, WordPress or plain hand-written pages. Because only the delivery layer is hosted, teams keep full control of presentation while the vendor handles deliverability, spam filtering and storage.

The engineering approach is worth noting: the public endpoint is intentionally kept small and fast so it can accept and persist a request immediately, while slower work such as sending email and triggering integrations happens afterwards. That design keeps visitors from waiting on a mail provider, and blocked submissions are excluded from quota so a bot cannot exhaust a monthly allowance.

**Pricing & Plans:** Free forever up to 250 submissions per month with unlimited forms and domains. Pro is $15 per month (billed yearly at $180) for 10,000 submissions, and Business is $40 per month (billed yearly at $480) for 20,000 submissions, with extra seats at $5 per seat per month.

- **One endpoint per form:** Every form gets its own URL that accepts a POST and delivers the payload to a chosen inbox, so static sites gain a working contact form without deploying a server.
- **Layered spam defence:** Honeypot fields, captcha options such as hCaptcha, reCAPTCHA and Turnstile, keyword and IP rules, rate limiting and an AI review layer all run before a message reaches you.
- **Searchable submission storage:** Submissions are stored in a dashboard that supports search, starred and archived views, delivery status, CSV or JSON export, and configurable retention windows.
- **Webhooks and a submissions API:** Forward each submission as JSON to your own URL or into Slack, Discord and Telegram, and pull records later through a read-only REST endpoint.
- **Notification and autoresponder control:** Set custom subject lines, reply-to addresses, intro text with field variables, autoresponder emails and a redirect to your own thank-you page.

**Strengths:** No server, database or backend code to deploy or patch; Spam blocked by filters never consumes the monthly message quota; Unlimited forms and domains even on the free tier; Every submission is both emailed and stored in a searchable dashboard

**Limitations:** Free tier is capped at 250 submissions per month; Custom sending domain requires a paid tier; The endpoint URL is public in your page source, so domain locking matters for abuse prevention

## OpnForm

OpnForm is a form-building platform aimed at teams that want modern form UX without the response caps and lock-in typical of commercial survey tools. The editor is drag-and-drop and supports both single-page and multi-step layouts, so a long intake questionnaire can be broken into a conversational flow. Fields can be governed by conditional logic, calculations and answer piping, and forms can be styled with custom themes, brand colours and fonts. AI assistance is available when you want it for drafting questions or fields, but it stays opt-in rather than being forced into the workflow.

What differentiates OpnForm most is its open-source posture. The full codebase is public and auditable, and organisations can choose between the vendor's hosted cloud, an EU-based cloud deployment, or running the software on their own infrastructure. That matters for companies with data-residency rules or internal security reviews. The product also ships team-oriented controls such as shared workspaces, roles and audit history for form and submission activity, along with SSO and SAML for enterprise accounts and 2FA support.

On the automation side, OpnForm connects to the tools teams already use. Submissions can flow to Slack, Discord or Telegram, sync to Google Sheets or Zapier, trigger notifications and routing rules, or be pulled through a documented REST API and webhooks. Payments are handled natively through Stripe, which makes it usable for registration fees and simple product orders. Forms can be distributed by link, embedded on a website or inside Notion, published on a custom domain, or exported as a QR code for offline collection.

**Pricing & Plans:** Freemium. A generous free tier includes unlimited form submissions with no per-response charges, and paid plans add more control, branding removal, team and enterprise features. EU hosting and self-hosting options are available; check the site's pricing page for current tiers.

- **Open-source, self-hostable form builder:** The full codebase is public and auditable, and you can run OpnForm on the vendor cloud, an EU-hosted instance, or your own infrastructure for complete data ownership.
- **AI assistance when you want it:** Optional AI help for building forms and fields, designed to stay out of the way when you would rather write everything yourself.
- **Smart logic and calculations:** Conditional logic, computed fields, answer piping, hidden fields and redirect-on-submit rules let one form adapt to many different respondents.
- **Unlimited submissions without per-response fees:** Collect as many responses as you need even on the free plan, with no hidden quotas or surprise overage charges.
- **Integrations, payments and API access:** Send data to Slack, Discord, Telegram, Google Sheets or Zapier, take payments via Stripe, and automate anything else with webhooks and a REST API.

**Strengths:** Genuinely open-source with a public codebase and self-hosting path; Unlimited submissions on the free tier with no per-response billing; Strong automation coverage through native integrations, webhooks and a REST API; Enterprise-ready controls including SSO, SAML, roles, audit history and EU hosting

**Limitations:** Self-hosting shifts update, backup and security responsibilities onto your own team; The deep feature set, especially logic and integrations, takes time to learn; Some enterprise compliance capabilities are still described as in progress rather than fully certified
